Obsessed with snowglobes

I admit I am super obsessed with snowglobes...at least making snowglobes. I will make them out of whatever I have handy at the moment. Dollar Tree has cute little vases that I found the other day that I was able to pair with 2 inch wood rounds from Michaels for 79 cents. A little mod podge, salt, glitter, a snow man and there you have a totally cute snow globe for under three bucks..check it out! Going to make a bunch up for upcoming craft fairs and see how they sell..What do you think a fair price is?
